This invention relates to levers for shaking grates and more particularly to levers for shaking the grates oflocomotive fire boxes.

In locomotives which are not equipped with 5 power shaking apparatus for the grates, it-' is customary to provide, on a grate bar or on a link which connects a plurality of gratebars, a suitably projecting stud or stub shaft with which a removable lever is adapted to cooperate for the purpose of shaking the grate bars.

of iron or steel.

Shaking levers are usually; from four to five feet longand require considerable expenditure of efi'ort on the part of the-fireeral instances such breakage has resulted in serious 1n ur1es to the fireman who was exerta ing great effort at the time of the breakage and was either precipitated against the hot rear wall of the fire box and burned or thrown to the floor of the cab compartment and injured. Unfortunately, defects in the metal occurring as a result of the upsetting or weld ing are not readily detected until the breakage occurs. The present invention seeks to overcome the above difficulties and to simplify the construction of the lever used for shaking grates;v I j It is thereforean object of the present invention to provide a novel and improved form of lever for shaking grates.

More particularly, it is the object of the invention to provide a grate shaking, lever formed in two parts,rincluding a bar having a handle at one end and an enlarged portion. at the opposite end adapted to be received in and permanently secured to a hollow seam- Heretofore, such levers have' been formed either by upsetting the end of a' wrought iron bar and piercing the same to provide a socket to slip over the stud or by 15 suitably welding a socket to the endof a bar less" member having 5 a socket extending beyond the end of the bar Other and furtherfeatures and objects of tl reinventieir will be more apparent to those skilled in the art upon a consideration of the accompanying drawings and following specificatinn, whereinis disclosed asingle; exemplary embodiment of the invention, lithe-ing understood, "however, that various changes may be niacle thereinsuch as -fa-ll wi-thirr the scope of the appende'd'cla-im without departingfronr the spirit ofthe invention.

F-gure Q'is a partial si'deelevation on an enlarged scale showing the sleeve in vertical Figure 3 is a transverse section taken on line 3-3 of Figure 2; and

Figure 4 is a vertical section taken on line 44: of Figure 2.

V A lever constructed according to the present invention comprises two essential parts, the bar 10 andthe tube 11. The bar is prefarably rolled or drop forged from open hearth steel and is more or less rectangular in cross section and tapers upwardly from the point 12 to the point 13 where it is 611- larged and made substantially cylindrical to form the handle 14; Below the point 12 there is a blunt wedge-like enlargement 15 which preferably has parallel sides 16 as shown in Figure 8 and converging edges 17. The cross section anywhere within the enlargement 15 is that of an elongated rectangle.

The tube portion 11 is preferably formed from a section of seamless steel tubing prop erly shaped to have one end fit over the en-" larged part 15 of the bar and the other end to provide the socket 18 adapted to fit over the stud on the grate bar. As shown in Figure.i2, the tube preferably is flared in bothdirections from the restricted center 19, but" its widest walls remain parallel to each other as do the'sides 16 of the enlarged portion of the bar. The upper end of the tube is so formed as to have an exact fit on the enlargement at the end of the bar which is then' i n is claimed as new andidesired to be secured driven into the tube, after which suitable holes are drilled through the two parts and fastening means, such as the rivets 20, applied so as to retain the two parts secured together. That portion of the tube extending below the end of the bar forms the socket 18 previously referred to.

By making the tube or socket of a piece 7 of seamless steel tubing, the likelihood of any flaw existing therein is reduced to a minimum and danger of accidents almost entirely elilninated. At the same time the bar can be more easily and cheaply constructed and can be made lighter in weight than heretofore.

Having thus described the invention, what by Letters Patent is:

Ina lever for shaking locomotive grates,

in combination, a metal shaker bar having said tubing and bar together and a portion of said tube extending beyond said bar and;

an enlarged portion at one end, saidportion vbeing rectangular in cross section and having two parallel faces and two faces converging toward the end of the bar, a length 'ofseamless steel tubing having walls of uniform thickness and substantially twice the, length of said enlarged portion, a portion of said tubing closely fitting over said enlarged portion of said bar, means fastening forming a socket to engage a shaker stud.
